Males are distinguishable from females by looking at the claws. Females have two small claws while males have one larger claw that they use for courtship and defense. The name "fiddler crab" comes from this claw - the crabs look like they are playing fiddles while waving their claws around!
Fiddler crabs, like all other crabs shed their skin! This molting occurs regularly as the crabs grow. They will literally crawl out of their skin, leaving behind the smaller shell. During this time the new shell is soft, making the crab more vulnerable to predation.
Fiddler crabs are important intertidal animals, living in marshes and estuaries along much of our coastlines. They are important food sources for many animals and can dig burrows in the mud up to 24 inches deep, aerating the swamp.

Guys, don't do it! Or do, I don't really care. I'm just here because I feel I owe it to the hobby, to the few noobs who would actually buy fiddler crabs and put them into a freshwater tank, to inform you all that fiddler crabs are not freshwater crabs. They are saltwater and should be placed in brackish water. In freshwater, they will slowly weekend and die over the course of a few weeks. That's what happened to the ones I bought 10 or so years ago when I first tried to get into fish keeping, back when Walmart sold them, and it broke my spirit. I didn't try to get back into fish for 9 years after that. Fiddler crabs, when kept in freshwater, will die. I'm leaving a 3 star review to remain as neutral as possible and not throw off any future reviews on this product page.
